Hydroxypropyl methyl cellulose, abbreviated as HPMC, is a type of cellulose polymer. This material, which is composed of carbon, hydrogen and oxygen atoms, is a fibrous white powder without odor and taste. This substance, which is also known as hypermellose, has a very high level of solubility in water. Due to its high cohesion, moisture absorption and high solubility, HPMC has various uses in different industries. Also, high pH stability, thickening ability, very high film-making ability, and very high enzyme resistance are other features of this fiber.
Industrial applications
Hydroxypropyl methyl cellulose is widely used in the production of building materials due to its high adhesion and cohesion. Putty powder, plaster, ceramic tiles, marble and cement are among the materials that this fiber is used in their construction. This material is also used due to its moisture retention feature to prevent hardening of cement and prevent cracks from forming in the grout. In addition, hydroxypropyl methyl cellulose is used as a dispersing agent. It is also used in the production of polyvinyl chloride. This substance is also used as a dispersing, thickening and stabilizing agent in the ink printing industry due to its high solubility. Using it as an adhesive in the manufacture of ceramic products and as a lubricant and softener in the manufacture of plastic products are other industrial applications of HPMC. Hydroxypropyl methyl cellulose is used in the food industry as a substitute for gelatin. to be This substance is also used in the baking industry as a substitute for gluten. This substance prevents the loss of water in the pieces of bread. For this reason, gluten-free bread is softer and gets old later.
